Here's a lovely picture from the Canberra DSN this morning, showing two of the workhorse 34-meter antennas communicating with the nearby GRAIL spacecraft. In the distance, the huge DSS-43 talks to the solar observatory STEREO-B.

The terrific launch photographer Ben Cooper is at the Cape waiting for GRAIL's Delta 2 rocket to take off, and last night he took this very cool photo.

Here's a few pretty pictures that were recently dusted off by Ted Stryk. Pioneer 10 and 11 passed by Jupiter on December 4, 1973, and December 3, 1974, respectively. Here are three pictures from those two encounters, in versions newly processed by Ted from scanned photographic prints found during a research trip to NASA's Ames Research Center.

The summer is winding to a close but it's not quite over for me -- by which I mean my children -- yet.

It's always awe-inspiring to see our great world as just a tiny spot within vast space. The latest spacecraft to get such a view of Earth and the Moon is the Jupiter-bound Juno.

Yesterday Cassini passed unusually close by Hyperion, the oddly shaped moon that orbits Saturn just beyond Titan. Among the many cool images captured during this flyby were three that I used to make this neato view of Hyperion's crescent.

I haven't checked in on Cassini lately. I went to the raw images page and found the frames for this very lovely, very close view of Saturn. It was taken by Cassini two days ago, as it was approaching periapsis.

Behold an amazing (if I do say so myself) video of Martian clouds in motion.

Dawn's images of Vesta show craters upon craters, but the longer I study the images, the wackier the craters look.

This photo is making the rounds of Twitter, Facebook, Google+, and whatever other social network you care to name today. It was shot by astronaut Ron Garan from the Space Station, and it's a meteor seen from above. Way cool.

Amateur astronomer Patrick Wiggins sent me this neat little animation of comet Garradd moving against background stars through an hour's worth of observing. I'm not any kind of astronomer but if I were I think I would get a kick out of looking at things that appear to move within one night of watching -- asteroids, comets, Jupiter's spots. I'm impatient that way.

I had to wait until the kids were in bed and the husband fed last night before I finally had time to sit down and really look at the Dawn images of Vesta. And I still hardly knew where to begin. This brand new world is just so different than others I've seen.

Now that Dawn's close enough to Vesta, we're seeing absolutely spectacular detail and tremendous diversity across Vesta's surface. As usual it'll probably take me a while to bring together all the new information, so as a stopgap I'm going to post an awesome image and a rotation movie.

In a story that I've been following for quite a while, Jupiter's southern equatorial belt, having faded to white in 2009, is now well on its way back to its former red glory.

The views from Opportunity of Endeavour's near and distant rim peaks are getting ever more vertical as Opportunity approaches Cape York.

Here's the latest image release from Dawn at Vesta, taken from an altitude about twice as high as that of their first mapping orbit.

A few weeks ago a producer for a public television space documentary asked me if I knew of any cool Cassini animations and my answer was,

Maybe it's my own peculiar variant of pareidolia, but every time I see a new image of Vesta I'm reminded of some different other lumpy body in the solar system. In the image released just now by the Dawn team, taken from 10,500 kilometers away, I'm seeing Hyperion.

Since jumping from the Boston Globe to the Atlantic with his signature galleries of striking images, Alan Taylor has continued to regularly feature space-themed photos. This week his In Focus feature looks back at the shuttle program with 61 images -- check it out!
